Genetica de la resistencia a roya amarilla en plantas adultas de trigo harinero
(Sociedad Mexicana de Fitogenética, 2009)
La roya lineal amarilla del trigo (Triticum aestivum L.) causada por Puccinia striiformis f. sp. tritici es una enfermedad de creciente importancia en los Valles Altos de México, pues llega a causar perdidas en el rendimiento ...
Field resistance of wheat (Triticum aestivum L.) genotypes from different countries to leaf rust (Puccinia triticina)
(The Scientific and Technology Research Council of Turkey, 2008)
Puccinia triticina causes leaf rust in wheat and results in severe yield losses in mild wheat growing areas of Turkey: Thrace, Marmara, Mediterranean, and Çukurova. A feasible way to avoid any damage is to grow slow rusting ...
Transferencia del gen Lr14a de trigos harineros a trigos cristalinos y expresion de la resistencia a roya de la hoja
(Sociedad Mexicana de Fitogenética, 2010)
El origen del gen de resistencia Lr14a a roya de la hoja causada por Puccinia triticina E. es el trigo tetraploide 'Yaroslav emmer' (Triticum dicoccum L.). En México, todas las razas de trigo harinero (T. aestivum) importantes ...
Mapping of wheat stripe rust resistance gene YrZH84 with RGAP markers and its application
(Institute of Crop Sciences, 2009)
Zhou 8425B, with an effective stripe rust resistance gene YrZH84, is a hall-mark parent line of wheat (Triticum aestivum L.) in the Yellow-Huai Rivers wheat growing region. An F2 population derived from the cross Zhou ...
Molecular mapping of powdery mildew resistance gene in wheat cultivar Jimai 22
(Institute of Crop Sciences, 2009)
Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important diseases of wheat (Triticum aestivum L.) worldwide. Breeding resistant wheat cultivars is the most economical and effective ...
Cloning and characterization of maize miRNAs involved in responses to nitrogen deficiency
(Public Library of Science, 2012)
Although recent studies indicated that miRNAs regulate plant adaptive responses to nutrient deprivation, the functional significance of miRNAs in adaptive responses to nitrogen (N) limitation remains to be explored. To ...
Evaluation of CIMMYT germplasm for resistance to leaf spotting diseases of wheat
(Czech Academy of Agricultural Sciences, 2011)
The leaf spotting disease complex is a major biotic constrain in enhancing grain production in the major wheat growing regions. Two leaf spotting diseases, tan spot, caused by an ascomycete fungus Pyrenophora tritici-repentis, ...
Genomic prediction of genetic values for resistance to wheat rusts
(Crop Science Society of America, 2012)
Durable resistance to the rust diseases of wheat (Triticum aestivum L.) can be achieved by developing lines that have race-nonspecific adult plant resistance conferred by multiple minor slow-rusting genes. Genomic selection ...
Postulated genes for resistance to stripe rust in selected CIMMYT and related wheats
(American Phytopathological Society (APS), 1989)
Infection type data were used to postulate the presence of stripe rust seedling resistance genes in 20 CIMMYT and related bread wheats. Yr3, Yr6, Yr7, and Yr9 were hypothesized to be present in 12 lines, either alone or ...
New genes for leaf rust resistance in CIMMYT durum wheats
(American Phytopathological Society (APS), 2005)
Leaf rust, caused by Puccinia triticina, has become an important disease of durum wheat (Triticum turgidum) in Mexico since the detection in 2001 of BBG/BN, a new race virulent on all common cultivars and on more than 80% ...
